IMPROVEMENT IN HORSE-POWER.

To all whom it may conce/m.'

Figurel is a perspective view of the machine, with our improvementsinplace.

Figurez, a plan view of the same.

Figure 3, a portion of the same, to illustrate one of the two obliquespur-wheels D, and the shaft, bevelled pinions, and boxes, or bearings.

The nature of our invention consists in the arrangement of the triplegear, in which the three distinct shafts have their bearings, on the twocross-pieces in -front of the supporting-frame, the lateral shafts beingin an oblique position; 'and each is provided with a spurwheel and twobevelled pinions, and receives motion from the cogs on the under side ofthe main wheel, which latter also drives a central shaft, provided witha bevelled pinion at its other end, which meshes between the bevelledpinions terminating the oblique shafts, while the enlarged spur-wheelsgive motion to the central jackshaft, which is in a line with thebefore-mentioned central shaft, but in separate bearings, anddisconnected from it, all the pinions and gear operating in harmony, andso as to promote the transfer of power and neutralize the upward ordown-pressure on the central jackshaft. y

The several drawings clearly illustrate this arrangement. Abriefexplanation, with reference to the letters marked thereon, will enableany one skilled in the art to make and use our invention.

The central cap and sweeps or levers are not shown, claiming no novelty.i Theobloug frame Q Q shows the cross-pieces R P in front, centralcrossbeam N, (and rear cross-piece S,) which supports the main wheel A,and gearing, which consists of the two spur-wheels D D', on theiroblique shafts M M', inclined from the sides toward a common centre. v

These shafts also support each a bevel-pinion, O, meshing into theco sonthe under side of the main or driving-wheel A, an' terminated by abevel-pinion, F

and F', respectively.

Between these last-named pinions is a similar pmion, G, connected with acentral shaft, L, which eX- tends to the rear cross-piece, and has abevel-pinion, o, meshing into the cogs on the under side ofthe mainwheel A aforesaid.

This shaft has its bearings on the front, central, and rear cross-pieces.P N S.

In a line with this shaft, but not connected with 1t, is the central orjack-shaft K, in boxes or bearings H i on the-cross-picces .P R.

This shaft has a pinion, E, which is actel upon or moved bythespur-Wheels D D', which act in concert, and neutralize the tendency ofbeing pressed up or down, and transfer their united power to the centralor jack-shaft, with its coupling connected, and calculated to driveother machinery.

All the shafts have their separate bearings, or boxes, H. v

Friction-pulleys c may be placed on the blank iiange above and beneath,as may be deemed most desirable.

B shows the central head, without the cap, for the lever-arms.

a, the spokes or cross-braces of the wheel A.

I, iig. l; shows the stout central pivot which supports the main wheel.

The operation is such, that the main wheel gives lnoi tion to threedistinct shafts, L M M', at three points of its circumference. Thebevel-gear on the ends' of the shafts M M again react upon the shaft L,or are rather aided by it from the vmain wheel and central shaft L,while the spur-wheels D D on the shafts M M impart their united power tothe intermediate pinion E on the jack-shaft and its connection.

Ve are aware that patent No. 77 ,945, May 19, 1868, shows a triple gearin a triangular frame, with two oblique and one central shaft, on whichlatter there is a larger cogged wheel in the centre of the main wheel,

which latter has the levers connected to the circnlnference, (therebeing no central pivot,) resting on bevelpinions, and held in positionby friction-Wheels, the supplemental shaft or jack-shaft `being parallelto 4and beneath the central shaft, the arrangementdilferingsubstantially in principle of operationand construe` tion; and wedisclaim the use of such a combination above referred to.

Nor do we claim the main wheel, with its cogs beneath, andcentral-bearing, or the blank anges, friction-rollers, and bevelledpinions, independently considered, for such are in common use but we arenot aware that the arrangement of spur-wheels D Dvon shafts, withpinions O E, were ever combined substantially with the main wheel anddriving-shafts in the manner shown and described. Therefore,

What we claim as our invention, and desire to secure by Letters Patent,is-

The arrangement ofthe spur-wheels D D on their oblique shafts M M, whichare provided with pinions O O and F F, together with the central shaftsK L, in a line with each other, with their respective plnions E G Ooperated by the main Wheel A, combined substantially in the manner andfor the purpose specified.
